A look at key moments this past week in the wrongful death trial in Los Angeles between Michael Jackson's mother, Katherine Jackson, and concert giant AEG Live LLC, and what is expected at court in the week ahead:

Jackson's mother wants a jury to determine that the promoter of Jackson's planned comeback concerts didn't properly investigate Dr. Conrad Murray, who was convicted of involuntary manslaughter by a criminal jury for Jackson's June 2009 death. AEG's attorney says the case is about personal choice, namely Jackson's decision to have Murray serve as his doctor and give him doses of a powerful anesthetic as a sleep aid. Millions, possibly billions, of dollars are at stake.

WHAT HAPPENED THIS PAST WEEK

Michael Jackson's Evolving Style

— An addiction and pain management expert, Dr. Sidney Schnoll, told jurors that there was no evidence in Jackson's medical records he reviewed that the singer was addicted to prescription medications. He told the panel that with proper treatment, Jackson could have lived a long life and continued to perform.

— Jurors heard from a human resources expert, Jean Seawright, who said AEG Live should have performed a comprehensive background check on Murray before agreeing to allow him to work on the Jackson's tour. She said the former cardiologist's initial $5 million request, and his expected $150,000 a month payday, were red flags and more investigation was warranted.

— A large, three-panel display of Jackson's history of medical treatments, including administrations of the anesthetic propofol dating back to 1997.

Life and Times: Michael Jackson

— The judge throw up her arms after an attorney for Katherine Jackson asked Seawright whether she had an opinion on whether AEG Live hired Conrad Murray, a key point in the case. Superior Court Judge Yvette Palazuelos stopped the proceedings to address the jury and tell them that they were the ones who would determine whether Murray was hired by the concert promoter.

— "Since he was going into treatment, I can only assume he didn't want to be a drug dependent person," Schnoll said regarding Jackson and his decision to enter rehab for prescription drug issues in 1993.

— "It was a red flag to me at the beginning of the process," Seawright said of Murray's initial fee request and agreement to work with Jackson for $150,000 a month.

— Jackie Jackson said his niece Paris Jackson is going to be fine and is getting better after being hospitalized last month for taking Motrin pills and cutting her arm with a kitchen knife. Jackie Jackson made his comments before the premiere of the Michael Jackson-themed Cirque du Soleil show "One" in Las Vegas.
